RELATED APPLICATIONS

This application claims the benefit of, and priority to, United States Provisional Patent Application 61/289,740 filed Dec. 23, 2009. The entirety of that application is incorporated by reference herein.

FIELD OF THE INVENTION

This invention relates generally to kettles. More specifically, the invention relates to a kettle with a trivet.

BACKGROUND OF THE INVENTION

Hot and warm beverages are popular beverage around the world. The beverages can include tea, coffee, or any other drink served at an elevated or reduced temperature. Many tea drinkers prefer to drink their tea hot, or at least above room temperature. This can be a challenge when attempting to serve or consume more than a single cup of tea, as the kettle may allow the tea to cool beyond a preferred consumption temperature, or the kettle itself may be too warm to place on certain surfaces. Thus, trivets are often used when placing kettles on sensitive surfaces, but the trivet can easily become separated from the kettle, or the kettle can be insecurely placed on the surface. In either event, the functionality of the trivet is either lost if the trivet cannot be located, or the kettle may spill. Additionally, due to custom, appearance, or personal preference, many people prefer to heat their water in a kettle separate from the serving kettle.

Therefore, it would be desirable to provide kettle that overcomes the aforementioned and other disadvantages.

DETAILED DESCRIPTION OF THE DRAWINGS

FIGS. 1-14 illustrate various aspects of a kettle in accordance with the invention. The kettle comprising an upper portion including a hollow center and a first opening and a second opening, a spout portion removably attached to the upper portion and removably attached to a base portion, wherein the spout portion includes a top spout side and a bottom spout side, and wherein the spout portion includes a variable diameter, a base portion including at least a base section, the base section comprising a magnetic material; and a trivet portion, the trivet portion at least partially comprised of a magnetic material, and wherein the trivet portion is sized to mate with the base section. In one embodiment, a strainer is disposed near the intersection of the base section and the spout portion. In one embodiment, the magnetic properties are enhanced based on temperature such that the magnetic material is configured to exhibit magnetic properties in response to the application of heat.

In one embodiment, the material comprises franklinite. In another embodiment, the material includes an AlNiCo magnet. In other embodiments, simple magnets are used. In other embodiments, threaded connections connect the upper portion and spout portion and between the spout portion and base portion. In one embodiment, the outer surface is at least partially covered with a temperature sensitive ink that changes color in response to heat and/or cold. In such embodiments, the ink is selected to reveal and/or hide a desired image, color, or graphic when the temperature reaches a certain desired temperature. Such temperature sensitive inks are available from numerous suppliers. Alternatively, standard or other inks can be used. In yet other embodiments, the upper portion includes a one way valve configured to allow water to be poured into the kettle via the larger diameter hole in the top portion, while only allowing liquid to be served from the kettle via the smaller first opening and second opening. In yet other embodiments, the upper portion includes a fitment configured to allow water to be poured into the kettle via the larger diameter hole in the top portion, while only allowing liquid to be served from the kettle via the smaller first opening and second opening.

In one embodiment, when hot water, or other hot liquids, is placed in the base portion, the base portion heats up, increasing its magnetic properties and adhering to the trivet. The trivet then protects against damaging any sensitive material that the trivet and kettle rest upon. The magnetic attraction further increases the stability of the kettle on the trivet, reducing accidental tips or spills. The hot water can then be infused with tea placed in the tea strainer, and the tea can be easily poured through the top portion.

In other embodiments, the magnetic properties of the material are not materially affected by the application of heat, and the trivet will magnetically adhere to the base portion regardless of the temperature of any liquid that may be present within the base portion.

Specifically, FIG. 1 illustrates a perspective view of a kettle 100. Kettle 100 includes a trivet portion 140 sized to mate with a base portion 130. Base portion 130 includes base section 135. The trivet portion 140 comprises a magnetic material, and the base section 135 includes a material configured to exhibit increased magnetic properties in response to the application of heat. Additionally, kettle 100 includes an upper portion 110 and a spout portion 120. Upper portion 110 includes a hollow center 112, as well as first opening 114 and second opening 116. Spout portion 120 includes a top spout side 122 and a bottom spout side 124 and includes a variable diameter. Not shown in FIG. 1 is a tea strainer included in the base portion in certain embodiments. The spout portion is removably attached to the base portion and also removably attached to the upper portion. The contours and shapes of the kettle illustrated in FIGS. 1 and 2 are exemplary designs.

In one embodiment, a connection between the upper portion and spout portion includes threads.
